Chapter 1. Project Research Summary State of the Art Summary Today web service has become a common approach to expose the services-applications over the network. It is the software system designed to support interoperability from machine to machine over the network. Web services are being used everywhere. Some specifications have been built or being built to improve Web service interoperability and to add more features. These are known as WS-* or Quality Of Service (QOS) of WSIT(Web Service Interoperability Technology). 1 These features are - message optimization, reliable messaging, security, bootstrapping and configuration, Currently these WSIT features are included in Netbeans Metro plug-in. Netbeans supports easy creation and modification of web services and these WSIT features through Metro Plug-in. 2 Netbeans supports top-down, bottom-up and even starting from scratch approach to create web services. We can edit or add WSIT features just by doing right clicking on project in Netbeans. Eclipse is another heavily used IDE to create different projects. Perhaps it is used more than Netbeans. Eclipse doesn't support direct creation of WSIT features. Eclipse is not as easy as Netbeans in creating Web services. There are some plug-ins available for eclipse, those support web service creation. Significant efforts have been done for the core functionalities to be added in eclipse in Axis2 and lomboz plug-ins. They have rich set of features to generate web service in eclipse. 3 Axis2 of Apache and lomboz are such plug-ins, but they don't support web service creation from scratch nor they provide WSIT or QoS features. Above mentioned plug-ins are open source and promised to deliver more features in their projects. So ultimately they don't support web service creation without having java class or WSDL. Of course we can implement every features described above in Netbeans through some external tools. By using external tools like Wsimport, Wsgen maven2 and SOAP UI or ant build script or CLI, we can implement web service features. 4 But it is little difficult as manually creating or modifying WSIT configuration is hard. So we have taken a step to build such a plug-in for eclipse that is replica of Metro plug-in in Netbeans. It will support creating web service from scratch, it will support adding or editing WSIT features ( or call it Metro features or QoS) just by doing right click on eclipse project. Chapter 2.

Jspwiki style: sortable
%% Dependencies
None. Deliverables
The following are the deliverables of this project: * An Eclipse IDE Plug-in that will provide the ability to use the complete Metro web services stack in Eclipse. The plug-in will be capable of creating and editing web services as well as creating web services client. * A Blog to publish and discuss issues related to the project. * In the final deliverables, the plug-in capabilities will also be documented in the form of user manual for the future reference and maintenance. Limitations
- Currently we will be concentrating on Creating and Editing Web Services part of the plug-in.
